IMPROVEMENT IN HAY ELEVATORS AND CONVEVERS.

Specification forming part of Letters Patent No. 195,615, datedSeptember 25, 1877 application filed August 18, 1877.

To all whom it may concern:

Be it known that I, IRWIN S. KRIoK, of Oonneautville, in the county ofCrawford and State of Pennsylvania, have invented a new and valuableImprovement in Hay-Carriers; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a side view of myhay-carrier; Fig. 2, a longitudinal vertical sectional view; Fig. 3, avertical sectional view, and Fig. 4 a sectional detail thereof.

The nature of my invention consists in the construction and arrangementof a carriage for hay-elevators, as will be hereinafter more fully setforth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents the beam or track for the carriage, secured under the peakof the roof of the barn to the rafters by means of brackets B. Each ofthese brackets is formed with three arms, as shown, one arm beingfastened to the top of the beam A, and the other two arms to the tworafters a suitable distance from their junction, so that these bracketsnot only support the beam A, but also form a brace to the rafters forstrengthening the same and keeping them in place.

0 represents the carriage, supported on the beam by means of flanges aor entering longitudinal grooves in the sides of the beam, or by meansof wheels or rollers mounted in the carriage, and running on top of thebeam, or on ways formed on or attached to the sides thereof. In thecarriage O is mounted a wheel, E, over which the hoisting-rope D passes.To ears on each side of the carriage is pivoted a lever, Gr, having atits lower end a semicircular rim, G formed on or attached to it. At theupper end of each lever G is formed a lug or arm, G which enters intothe interior of the carriage through a slot in the side thereof. Thesetwo arms or lugs support a latch, H, pivoted in the upper part of thecarriage. This latch has. a shoulder at b, which catches in and againsta casting, I, secured in the under side of the beam A. This casting isconstructed with a longitudinal slot forming a shoulder, 11, near eachend, and in the center is a crossbar with a bar, J, runninglongitudinally with the beam, and having its ends beveled, as shown.Within the carriage O is a verticallysliding plunger, L, provided at itsupper end with cams L L, projecting through slots in the sides of thecarriage, and at the lower end it has a head, L as shown. Each lever Gis operated upon by a spring, K, to throw the arm or lug G inward intothe carriage under the latch H.

On the hoisting-rope D, a suitable distance above the hay-fork, issecured a circular plate or disk, P, which is formed with a semi-tubulararm, R, to encircle one-half of the rope. This arm is formed with aclip, S, which surrounds another semi-tubular arm, R, driven downthrough the eye in the disk P, and then clamped by means of a set-screw,S. The inner or concave surfaces of the tubular arms R R are madetoothed or corrugated to bind firmly on the cord.

When the carriage moves on the beam A, and as it approaches thestopping-point, the front curved end of the latch H strikes the beveledend of the bar J, whereby the latch is raised from between the arms Gand the spring K, acting upon the levers G, throws said arms inward,preventing the latch from dropping down again, and the shoulder b of thelatch is caught against the shoulder d of the casting I, so that thecarriage is thereby locked in position.

It will be noticed that when in this position the flaring rims G at thelower ends of the levers are spread apart or separated. Now, as the loadis raised, the disk P passes upward between the rims G and as it strikesthe head L it raises the plunger L, which, by means of the cams L throwsoutward the upper ends of the levers G, causing the arms Gr to bewithdrawn from under the latch H, allowing the same to drop down,thereby releasing the carriage and allowing it to move along on the beamA. This movement of the levers G, caused by the cams L, as described,throws the rims G inward under the plate or disk P, so as to prevent itsdownward movement, and thus support the load while it is being conveyedto the designated spot, where the fork is unloaded. The carriage is thenreturned, and, as the latch is raised again, the plate P is released anddescends with the fork.

The carriage may be made to work from either end, the casting I beingfor that purpose made exactly alike on both sides of its center.

This hay-elevator carriage is simple in construction, easily operated,and not liable to get out of order.

The disk P may be adjusted at any point desired on the rope, and can beeasily changed to suit circumstances.

What I claim as new, and desire to secure by Letters Patent, is-

1. The casting I, formed with the shoulders d d, and provided with thependent bar J, having beveled ends, substantially as and for thepurposes set forth.

2. The gravitating latch H, formed with the shoulders b, in combinationwith the supporting-arms G and casting I J, substantially as and for thepurpose set forth.

3. The pivoted levers G G, formed with the rims G G and arms G; G incombination with the cams L L and springs K K, substantiall y as and forthe purposes set forth.

4. The plunger L, formed with the cams L and head [1 ,111 combinationwith the levers G, as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
